Serial Integer Writer

/*
 * Serial Integer Writer, by Pedro Tome'
 * Version 0.01
 *
 * Writes/sends integer numbers to the Serial buffer by converting them
 * into an ASCII string.
 *
 * Use this code if you want to send integer values to another Arduino,
 * which should have the Serial Integer Reader code, by Pedro Tome'.
 *
 * Example:
 * A temperature sensor reads the value decValue = 1234.
 * The ASCII string "1234" will be sent to the Serial buffer.
 *
 * The maximum value is 65535 due to "decValue" being an unsigned int.
